Belgium has halted a planned Chinese takeover of Noordzee Helikopters Vlaanderen (NHV), a helicopter operator headquartered in Ostend, on the grounds that it posed unacceptable risks to national security. The country's Interfederal Screening Commission, a body that reviews large investments by non-European organisations, investigated the proposed deal and raised alarm over its implications. Belgian Economy Minister David Clarinval confirmed the transaction would not proceed, citing "risks to national security, Belgium's strategic interests, and possible links with the defence sector."

NHV, which has been owned since 2013 by French investment firm Ardian, employs around 400 people and operates a fleet of roughly 30 helicopters. The company transports technicians and engineers to offshore wind farms and oil platforms across Europe, including operations in the Netherlands — from a base in Den Helder and in the port of Rotterdam, where its helicopters deliver maritime pilots onto vessels when rough weather prevents the use of small boats. The planned buyer was GD Helicopter Finance (GDHF), an Irish subsidiary of the Chinese aviation group GDAT. The sale had been scheduled for completion in early 2026.

A separate and particularly sensitive dimension to the case involved Belgium's defence sector. Last year, the Belgian military purchased 20 Airbus H145M helicopters, with Airbus responsible for their maintenance. NHV was in the running to serve as an Airbus subcontractor for that work. Had the sale gone through, a Chinese-controlled company would have gained access to Belgium's new military helicopter fleet. Defence sources had already expressed concern in February, with one senior figure describing the prospect of China having visibility into Belgian air systems as "a bridge too far."

The Belgian government described its decision as "entirely exceptional," noting it is the first time in three years that such a foreign investment has been blocked. Minister Clarinval was nonetheless careful to stress that Belgium remains open to foreign investment in general, saying the Screening Commission exists not to discourage investment but to ensure that national security, critical infrastructure, and strategic autonomy are not placed at risk.

The case reflects a broader trend across Europe of heightened scrutiny over Chinese acquisitions in sectors deemed strategically sensitive, from energy infrastructure to defence supply chains. For Belgium and its neighbours, NHV's role in keeping offshore energy installations operational gives the company an outsized importance relative to its modest size.
